Proper attire for interview -academic job

Question

I want to know whether it is appropriate to wear blue jacket and grey trouser/pant for a job interview.I am comparing this with a suit in which color of a jacket and trouser is same.

Answer 1

1 "step better" than what you would wear if you worked there.  You do not want to be under dressed or overdressed.  If they were shorts and t-shirts, you wear long pants and a polo shirt.  If they where dockers, you were dress pants, if they were dress pants, you were a suit, ...

You do not want to look out of place since the interviewer is trying to figure out if you will fit in at the company or not.

Answer 2

A suit is ideal.

Answer 3

When in doubt, stick with the suit.
